Flowmaster Super 44 Series Mufflers Reviews

Sounds awesome, perfect deep rumble on my f150. Have scared a few people taking off at a light when driving in the city. Has the perfect deep rumble that fits my truck perfectly. Very easy to install. Had to to come with a custom way to hold it up, used some strap clamps and worked perfect. Overall great buy.

Flowmaster Street Performance Mufflers Reviews

Love the low rumble my truck makes now!!
I did Not install this myself, Took it to a muffler shop had them do it.
I also did Not take out the exhaust resonator on my super crew cab truck,
And it sounds fine to me.
I get alot of comments about tone of my truck!
Very happy customer!!

Flowmaster Super 10 Series Mufflers Reviews

If you want a deep aggressive sounding exhaust look no further the super 10 is the muffler for you. I had it installed on a 1999 f150 5.4l v8 and it really brings out the v8 sound. I had it dumped right before the rear axel and it doesn't drone that bad you do here it at highway speeds but it is a flowmaster so it will have a bit of drone. I would definitely buy this muffler again
